Structure of a UCC/EAN-128 Barcode

The UCC/EAN-128 barcode, also known as GS1-128 or EAN-128, is a linear, variable-length symbology that encodes data using a combination of Application Identifier (AI) and data fields. The barcode structure consists of three parts: the start character, the data encoded using AI and data fields, and the stop character.

UCC/EAN-128 Barcode Structure

The start character of the UCC/EAN-128 barcode is usually the Code 128 start character. It is followed by an AI, which is a two, three, or four-digit number that indicates the type of data that follows. The AI is used to identify the data field and its length. For example, AI 01 indicates that the data field contains a GTIN (Global Trade Item Number), and its length is 14 digits.

After the AI, the data field follows, which contains the actual data to be encoded in the barcode. The length of the data field is determined by the AI. If the AI indicates a fixed length, the data field will be of that length. If the AI indicates a variable length, the length of the data field can vary.

In addition to the AI and data fields, the UCC/EAN-128 barcode also allows for optional check digits to be included. Check digits can be used to verify the accuracy of the data encoded in the barcode. The stop character of the UCC/EAN-128 barcode is usually the Code 128 stop character. It signals the end of the barcode and indicates that the scanner should stop reading the barcode.

Conclusion: The UCC/EAN-128 barcode structure provides a flexible and efficient way to encode a wide range of data types and lengths.
